Higher ratedRanked #1 in Best Bike Racks for Cars
Kuat Piston Pro X
$1,493as of Jun 7

The Piston Pro X is the no-compromise pick: hydraulic piston arms make it the easiest rack to load, it swallows fat tires and heavy e-bikes, and the integrated light bar is a genuine safety upgrade. The catch is the price and the weight. If budget is no object and you carry heavy bikes, nothing else loads this easily.

Strengths
  • One-Touch hydraulic piston arms clamp the front tire with one hand, the easiest loading of any rack tested
  • Holds 67 lbs per tray on a 2-inch hitch, enough for most full-power e-bikes
  • Fits fat-bike tires up to 5 inches and wheels from 18 to 32 inches without an adapter
Watch-outs
  • At $1,589 it is one of the most expensive two-bike platform racks sold
  • 64 lb rack weight makes it a two-person job to install and remove from the hitch
  • LED light wiring is one more connection that can fail or get pinched
Thule OutWay Hanging 2 Trunk Bike Rack
Ranked #5 in Best Bike Racks for Cars
Thule OutWay Hanging 2 Trunk Bike Rack
$360as of Jun 7

The OutWay Hanging 2 is the pick for anyone without a hitch. Thule's steel security cables make it the most stable hanging trunk rack reviewers have tested, it folds small, and it locks both ways. The compromises are inherent to the format: a 33-pound bike limit, the need for a horizontal top tube, and more movement than any platform rack.

Strengths
  • No hitch required, the cheapest way to carry two bikes on most cars
  • Steel security cables lock both the rack to the car and the bikes to the rack
  • Steel cables stay taut and stable where nylon straps on rivals sag
Watch-outs
  • 33 lb per-bike limit excludes e-bikes and heavy mountain bikes
  • Hanging design needs a horizontal top tube or a frame adapter for many bikes
  • Bikes touch the rack arms, with more sway than any platform hitch rack

How they stack up

Kuat Piston Pro X

The most refined rack here and the easiest to load. The Thule Verse matches it for ergonomics at a lower price but lacks the hydraulic arms and light bar. The Yakima StageTwo costs far less and carries a heavier 70 lb bike, while the Kuat Sherpa 2.0 is the lightweight value alternative from the same brand.

Thule OutWay Hanging 2 Trunk Bike Rack

The only trunk-mount option here and the budget entry point. It carries less weight and is far less stable than the platform hitch racks: the Kuat Piston Pro X, Thule Verse, Yakima StageTwo, and Kuat Sherpa 2.0 all need a hitch but hold heavier bikes more securely. Pick the OutWay only if you cannot or will not install a hitch.
